Please help me i dont know what the answer is ??

To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:
\frac{180}{3} = 60
Therefore, the measure of the triangle's angle is 60°

Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of 90°.

Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:
90=x+60+12 \\ 90=x+72 \\ 90-72=(x+72)-72 \\ 18=x

The missing angle measure, angle x, equals 18°.

Hope this helps!

I need help with this pls ASAP
olganol [36]

Answer:

It's B.

Step-by-step explanation:

3 × 10 + 2 = 30, not 50.

3 × 17 + 2 = 53, not 50.

Which means it has to be a number in between.

So, 152 and 156, are definitely not the answer. Which leaves 16.
